Virtual duplex systems have emerged as an alternative to traditional duplex systems, trading structural for temporal redundancy. When used in dependable embedded systems, virtual duplex systems provide a cost benefit because they require only one instead of two processors. In order to lighten the burden of this single processor, and in order to obey(More)
The SB-PRAM is an experimental multiprocessor architecture with a shared address space and synchronously running threads, i.e. giving the illusion to work on a PRAM. A 4-processor prototype has been completed while a 64-processor prototype is under construction. We investigate the detection and handling of single bit errors occuring during transmission of(More)
